CORN-SHELLER.

Specification of Letters Patent No. 20,266, dated May 18, 1858.

- 4 is a vertical transverse section through the line 00 w of Fig. 1.

A A A is the frame of the machine. G is a balance or fly wheel.

13 is a cylinder made of cast iron as follows to wit, the heads 0 0 (seeFig. are cast with a gudgeon or axle 79 p on each; 6, 7, 8, 9, 10, 11,are staves also of cast iron with shelling teeth cast on their convexside. These staves may be of any desired width to suit the circle of theheads 0, 0, the end of the staves fit in a groove around the heads 0, 0,and are fastened together either by rods passing through the wholelength of the cylinder or by screws as may be desired.

C G are two cog whee-ls running on the axles of the cylinder. The flywheel is also hung on the axle of the cylinder but fastened by a key orpin so as to revolve with it.

D is a small cog wheel on one end of the axle 77 which gears into thelarge cog wheel E; on the other end of the shaft of the wheel E is asmall cog wheel which gears into the wheel C or there may be two smallcog wheels on the same shaft of the wheel E gearing into the two wheelsC, C. The wheels C, C, are attached to each other by means of thefeeding strips 1, 2, 3, at, 5, (see Figs. 1 and 4) the ends of whichpass into mortises in the wheels C, C. These rods are of sufficientwidth apart to let an ear of corn pass in between them against thecylinder B, and as they revolve much slower than the cylinder they keepthe corn a sufficient time against the cylinder to shell it and at thesame time carry the cob around and discharge it over the fingers I I Iand over the apron vH which carries them oif from the machine. Under thecylinder B is a concave composed of a number of pieces 'of wood runningparallel with the cylinder one of which is represented at T Fig. 2. 2',2T, 2', z, are spring fingers of iron or other suitable material bent ina circle somewhat larger than the circle of the feeding strips 1, 2, 3,4c, 5. The piece of wood T has a groove in each end as shown at n. Thesegrooves work on guide stri 3s fastened to the end board-of the concave,R, is a steel spring bent in the shape shown on drawing Fig. 2 andbolted on the bottom of the frame of the machine by the screw bolts, S.The corn to be shelled is dropped in the hopper L and rolls down betweenthe strips 1, 2, 3, 4, 5, and by them is carried down and around thecylinder, B, and is pressed up against the cylinder by the fingers z 2'i 2' Fig. 2 with sufiicient force to shell the corn, while the spring R,accommodates the concave to the size of the ears of corn pressing thepoint and butt of the ear up equally. The corn when shelled passesbetween the pieces of wood T which are some two inches apart and passesout through the spout N. J is a feed board made to slide under thebottom of the hopper K to regulate the feed. The machine is propelled bya crank on one arm of the fly wheel C. e

What I claim as my invention and desire to secure by Letters Patent, is-

The shelling cylinder B constructed as described, revolving within thefeeding cylinder, in combination with the feed regulating slide J,concave T T and springs R, fingers i, discharging apron H, and spout Nwhen the several parts are constructed, relatively arranged, andoperated in the manner and for the purposes set forth.
